zinc dust

An example is the conversion of pentafluorobenzoic acid to 3,4,5-tetrafluorobenzoic acid in a reaction of zinc dust in aqueous ammonia.

Phenylsulfinic acid can be prepared in several ways, most easily through reduction of sulfonyl chlorides with zinc dust or iron.

The organozinc reagent, also called a 'Reformatsky enolate', is prepared by treating an alpha-halo ester with zinc dust.

It uses zinc dust and steam to remove copper, cadmium, cobalt, and nickel, which would interfere with the electrolysis process.

In related reactions, 1,2-dibromocompounds are debrominated by zinc dust to give alkenes and geminal dihalides can react with strong bases to give carbenes.

The metal is recovered from the "pregnant solution" by reduction with zinc dust or by adsorption onto activated carbon.

A laboratory examination showed that the zinc dust reducing agent was fully oxidised, showing that the kit was at least four years old.

Then, in 1866, Adolf von Baeyer reduced oxindole to indole using zinc dust.

Historically, treatment of haloketones with zinc dust in the Reformatsky reaction was one of the first reliable methods for generating unstabilized enolates.

We are if you know of a place where we could get ingredients like iodine crystals, ammonium nitrate, and zinc dust.
